NAME
pppdec - decode ppp conversations
SYNOPSIS
pppdec [ -a ][ -d ] [ file... ]
DESCRIPTION
pppdec decodes the given ppp logfiles (standard input) to a
textural description. The -a option causes all packets,
even those corrupted, to be decoded. Internal pppdec debug
may be enabled with -d, multiple instances increase the
quantity of the chatter.
The logfiles pppdec expects are simple, consisting of lines
of hex byte values prefixed by either TX or RX indicating
the part of the conversation they apply to; Any other text
is ignored.
EXAMPLE LOGFILE
PPP connecting
RX 7f 34 54 32 e3 2 c3 2 33 2 4f 32
TX 73 482 2 f f6 e9 32 98 88 f4 27
BUGS
pppdec was designed for debugging problems in establishing
connections and therefore makes little attempt to decode IP
packets.
The logfile parser is poor, it should be more tolerant.
